Abstract: Water is a precious natural resource that is necessary to sustain life. At the same time, discharge of effluents and domestic sewage with inadequate treatment or without treatment increase the load of pollutants and contaminants in the aquatic resources and threatens the balance of ecosystem. We can reduce the water demand up to the certain extent but basic water demand will be always there, as water is a human right and necessary to sustain life. This leads to the necessity to manage water pollution. Water (prevention & control of pollution) Act, 1974 is the main instrument for water pollution governance in India. However, according to the report published by CPCB, India have 43 critically polluted industrial clusters and 302 critically polluted river stretches. This shows that, there are many serious lacunas in the current governance system. In the above context, the concept of water footprint is the important tool to analyse water pollution. The term Water footprint was introduced by the team of Arjen Y. Hoekstra in 2002. Water footprint is an indicator of fresh water use which looks at direct and indirect water use of a consumer or producer. It is a comprehensive indicator of fresh water resources appropriation. The National Water Policy 2012 suggests that water footprint analysis should be included in project appraisal and environment impact assessment for water uses, particularly for industrial projects. In this context, this research aims to examine grey water footprint of industries linked with Phase I & ll CETPs of Dombivali MIDC. The research also aims to find out capacity of the Ulhas river, a critically polluted river (where the effluent from CETPs is discharged) to assimilate the load of pollutants and link it with the water availability and water pollution governance, through a quantitative research. Further, the study also throws light on deficiencies in the present water pollution governance system which will limit the application of grey water footprint as an instrument of water pollution governance.
